/**
 * @brief This preload controls 'UserDelete' action of the user module in the public side.
 * 
 * Basically, Package_Legacy deletes all informations of the user who want to delete self
 * account. But, if you want to control it, this file is good sample. This sample doesn't
 * delete the user's informations from DB. Instead, this removes the user from groups and
 * moves the user to the special group indicated by RESIGN_USER_GROUP_ID. 
 * 
 * At the beginning, you have to prepare the special group that doesn't have login-right.
 * Next, you input GROUP-ID of the special group into RESIGN_USER_GROUP_ID.
 * 
 * define("RESIGN_USER_GROUP_ID", {here});
 * 
 * Finally, you move this preload file to /preload of your site.
 * 
 * Notes that this preload doesn't give effect when you delete a user in the control panel.
